MACHINE FOR INSERTING ORNAMENTS.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed January 16, 1905. serial No. 241,254.

specification, like letters on the drawings representing like parts. i

This invention has for its object the production of apparatus by which to insert a plurality of ornaments in stock at one operation.

My invention is of especial advantage in setting ornaments of metal in leather for use as bridle fronts, dog collars and the like.

In accordance with my invention I provide a holder for a plurality of ornaments, and as shown I have provided means for positioning the stock or leather in which the prongs of the ornaments are to be set. With this holder I employ a support having clenching cavities and a guide to coact with the holder to insure that the prongs of the ornaments shall correctly enter the clenching cavities. To drive at one operation a plurality of ornaments I have attached a driver carrier to the lower end of a bar, and the carrier is provided with a series of detachable drivers shaped to correspond with the particular shape of the ornament to be driven.

Figure 1, on a small scale, shows a machine in which my apparatus may be handled Fig. 2 shows my apparatus detached from the machine; Fig. 3 is a top view of the holder; Fig. 4 is a section of the parts, Fig. 3, with an ornament in a pocket of the holder; Fig. 5 is a view of the same parts showing the prongs of an ornament clenched in the stock; and Fig. 6 shows a piece of stock containing ornaments.

The head A, bar A, spring A acting normally to raise the bar, the treadle controlled lever A, to depress the bar, and the hollow post A are and may be of usual shape. My novel apparatus comprises a support B having a guide B made as an upwardly extended flange and provided with a stud B that enters a hole in the post A and is held therein by a set screw B This support has clenching cavities b and a central groove b and as shown the inner side of flange B has one or more stops 1) that enter notches b in the rear edge of the holder, see Fig. 3.

The holder C has a series of pockets 0, each having suitable prong guides 0. These pockets will vary in shape according to the shape of the ornament D to be driven. The under side of the holder is provided with a groove 2, see Figs. {1 and 5, of a width and depth corresponding with the width and I thickness of the stock or strip, it may be, of

leather cm which the prongs (Z of the ornaments are driven as they are clenched in the stock as represented in Fig. 5. At one end the holder C has at its under side a clamp D attached to a rod D normally elevated by a spring D acting on the head of the rod. The clamp has a guide pin D and the clamp en ters the groove 2 of the support. To position the stock a in the holder that it may receive the ornaments, the rod D will be depressed to lower the clamp that the end of the stock may be inserted between the clamp, and the under side of the holder as shown at the right in Fig. 2, and in this position the rod D constitutes an end gage for the strip 6. It will be understood that a strip may be applied uickly in the groove 2 at the under side oi the holder either before or after inserting the ornaments in the pockets or spaces thereof and the holder, no matter how many ornaments it may contain, may then be laid on the support B with one edge against the flange of the support, and a projection b will enter a notch 12 and register the holder so that as the drivers, to be described, descend they will correctly meet the heads of and drive the ornaments.

The carrier F sustaining the plurality of drivers F has a stud f to enter a hole in a collar at the lower end of the bar where it is held by a set screw f The carrier has a series of holes in which are entered the shanks f 3 of the drivers and are confined in position by a set screw f theend of which enters an annular groove in said shank. Fig. 3 shows a few of these drivers in position.

In the use of my apparatus I may fill all the pockets with ornaments and drive them all at one operation, in which event I would have a driver for each ornament, or I may fill the pockets and employ two or more drivers and move the holder longitudinally over the support and under the drivers.

It will be noticed in operating my apparatus that the holder C may be readily removed from the support B and that when inverted the leather strip which is to receive the ornaments may be laid in the groove at the under side of said holder, the side edges of the strip meeting the side walls of the groove. The clamp D having been moved away from the under side of the holder, the end of the strip may be inserted between the clamp D and the under side of the holder and abut the rod D which constitutes an end gage. I am aware that devices have been made in which the ends of a leather strip might be butted, said devices being constructed to receive staples the prongs of which might be driven through the butted ends of the belt, the prongs being clenched in grooves on the plate supporting the under side of the belt, and such construction is not herein claimed.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1 In apparatus of the class described, a holder having a plurality of pockets to receive a plurality of ornaments, and grooved longitudinally at its lower side for the reception of stock into which the ornaments are to be set.

2. In apparatus of the class described, a holder having a plurality of pockets to receive a plurality of ornaments, said holder being grooved longitudinally at its under side to receive the stock in which the ornaments are to be set the side walls of the groove positioning the side edges of the stock.

3. In apparatus of the class described, a holder having a plurality of pockets to receive a plurality of ornaments, said holder being grooved longitudinally at its under side to receive the leather strip in which the ornaments are to be set, and a gage for the end of said strip.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

THOMAS L. SHERMAN.
